[JBoss Seam] - How to use conversationPropagation=
by tazo
During an conversation i would like to create new conversations (not nested) with custom conversationIds. I added next code to my page:
| <h:commandLink action="#{actionBean.show}" rendered="#{!entity.available}" value="X">
| <s:conversationPropagation type="none" />
| <f:param name="name" value="#{entity.name}" />
| </h:commandLink>
|
But it doesn't work as i expected: then i click this link i stay at same page: it doesn't contain info from old conversation (conversation propagation is really suppressed) and facesMessages input cantains "No conversation". During submit my custom action does not take control. If i remove <s:conversationPropagation> i get exception, because "actionBean.show" is annotated with @Begin.
What i want: i have conversations which contain different permutations of same entities. I takes much time to retrieve detailed info about these entities. I would like save obtained info in conversations with custom Ids, so Seam could optimize access to info already stored in memory.

[JBoss Seam] - About Deploy-unit to develop a big project by Seam
by keiuske
For example, it supposes that X-system has the following structure.
X-system
Login, Estimation, Reservation, Acceptance of the Order, Sales
And, JBOSS-SEAM Project has the following structure.
X.EAR
X.JAR
Login.Class
Estimation.Class
Reservation.Class
Order.Class
Sales.Class
X.WAR
Login.Jsp
Estimation.Jsp
Reservation.Jsp
Order.Jsp
Sales.Jsp
When false is in the Estimation-Class, the Estimation-Class is modified.
Then the Deploy-unit changes to X.EAR. And Login, Reservation, Order, Stocking and Sales Classes that without false are not deployed, service is stopped.
Is there the method to avoid stopping of a service?
I considered two kinds of methods. But these methods are not better solutions.
1. It supposes that the Estimation, the Reservation, and others were changed into the separate Deploy-unit.
Ex. Login.ear, Estimation.ear, Reservation.ear, Order.ear, Sales.ear
Then, the Class information of Estimation cannot be taken over to Reservation. And the Class information of Reservation cannot be taken over to Order?.
These problems occur.
Can @In-Annotation be used in the separate Deploy-unit?
Moreover, when the Common-Class is created, there is no good method to refer to the information from each Deploy-unit.
2. X.ear, X.jar, X.war were deployed per folder. And the Class-file of contents was replaced.
Then Jsp in war was changed. However the Class-file was not changed.

[JBoss Portal] - Re: selecting suitable UI technology
by sohil.shah＠jboss.com
JSF is an excellent technology to implement complex MVC related applications both in standalone web environment as well as in a portal environment.
We have adopted JSF exclusively to write a bunch of our applications here at JBoss. One of the applications that is being rearchitected using JSF/portal is our Forums technology which is currenly running on a framework called Nukes.
I agree, there are some implementation-level workarounds that have to be done especially with handling attachments, etc and the usecases you mentioned, but overall it fits like a glove for development on portal.
Also, there is support from the industry for JSF since there is already a JCP spec out there to build a standard-based bridge between portal and JSF technology. Industry support for technology you want to adopt for your overall architectutre is always a safe feeling.
My two cents
Thanks
Sohil
